First Reading: Deuteronomy 4:1, 5-9
1 And now, O Israel, hear the commandments and judgments which I teach thee: that doing them, thou mayst live, and entering in mayst possess the land which the Lord the God of your fathers will give you.
5 You know that I have taught you statutes and justices, as the Lord my God hath commanded me: so shall you do them in the land which you shall possess:
6 And you shall observe, and fulfill them in practice. For this is your wisdom, and understanding in the sight of nations, that hearing all these precepts, they may say: Behold a wise and understanding people, a great nation.
7 Neither is there any other nation so great, that hath gods so nigh them, as our God is present to all our petitions.
8 For what other nation is there so renowned that hath ceremonies, and just judgments, and all the law, which I will set forth this day before your eyes?
9 Keep thyself therefore, and thy soul carefully. Forget not the words that thy eyes have seen, and let them not go out of thy heart all the days of thy life. Thou shalt teach them to thy sons and to thy grandsons,
Responsorial Psalm: Psalms 147: 12-13, 15-16, 19-20
12 Praise the Lord, O Jerusalem: praise thy God, O Sion.
13 Because he hath strengthened the bolts of thy gates, he hath blessed thy children within thee.
15 Who sendeth forth his speech to the earth: his word runneth swiftly.
16 Who giveth snow like wool: scattereth mists like ashes.
19 Who declareth his word to Jacob: his justices and his judgments to Israel.
20 He hath not done in like manner to every nation: and his judgments he hath not made manifest to them. Alleluia.
Gospel: Matthew 5: 17-19
17 Do not think that I am come to destroy the law, or the prophets. I am not come to destroy, but to fulfill.
18 For amen I say unto you, till heaven and earth pass, one jot, or one tittle shall not pass of the law, till all be fulfilled.
19 He therefore that shall break one of these least commandments, and shall so teach men, shall be called the least in the kingdom of heaven. But he that shall do and teach, he shall be called great in the kingdom of heaven.
